Princess Stove Robertshaw Regulator
I repiped all the propane lines. The good news is everything works. Except the oven. Tell me if I screwed up.
The Robertshaw control is a fine piece of engineering. It does not have an igniter, nor does it have an automatic gas shut off valve. It does have a pilot and a two stage burner. It modulates between high and low fire based on the setting of the thermostat and the heat in the oven, measured by a capillary bulb.
I had the capillary bulb in and out a few times while installing the range top and oven, but I never disconnected it from the valve. I think it looks ok.
The problem is the thermostat will not control. I have adjusted the low heat setting and adjusted the calibration, but now the temp just keeps rising until it hits 450F.
Do I take the valve apart and clean it? This regulator is so old it can be taken apart and cleaned by the user. Or is the capillary tube pinched? Can the capillary tube be replaced?
Third option, and my least favorite, would be a replacement valve. Any recommendations?
